EEG / Sleep Stages / Arousals
Sleep stages
Wake, N1, N2, N3 and REM identified from EEG, EOG and chin EMG.
Educational reference, not a diagnostic tool. A scored event, an elevated index and a clinical diagnosis are different things. Follow your facility’s scoring manual, notification policies and clinical protocols.
- Wake: posterior alpha with eyes closed.
- N2: spindles and K-complexes.
- N3: high-amplitude slow waves.
- REM: rapid eye movements, low chin tone.
